Lethal

Formed in Kentucky in 1982 by the Cook brothers Eric and Glen,
Lethal scored some fine reviews for their 1990 debut, Programmed,
a solid progressive metal album in the early
Queensryche mold.
It would be five years before a followup EP (Your Favorite God)
was released, followed by Poison Seed a year later in 1996.
By this time, though, a major style change had occurred, the band
dropping the
Queensryche/progressive tendencies and instead opting for a heavier,
slightly grunge influence instead.
Whether because of the style change or not, they disappeared from
view soon afterward.
They came back together in June 2006, and are apparently still active.
